Now since all requirements are met, the next topic will guide you on how to start your first project.

This guide helps you on the first steps using ESP-IDF. Follow this guide to start a new project on the ESP32-S3 and build, flash, and monitor the device output.

Note

If you have not yet installed ESP-IDF, please go to Installation and follow the instruction in order to get all the software needed to use this guide.

# Start a Project

Now you are ready to prepare your application for ESP32-S3. You can start with get-started/hello_world project from examples directory in ESP-IDF.

Important

The ESP-IDF build system does not support spaces in the paths to either ESP-IDF or to projects.

Copy the project get-started/hello_world to `~/esp` directory:

    cd ~/esp
    cp -r $IDF_PATH/examples/get-started/hello_world .

Note

There is a range of example projects in the examples directory in ESP-IDF. You can copy any project in the same way as presented above and run it. It is also possible to build examples in-place without copying them first.

# Connect Your Device

Now connect your ESP32-S3 board to the computer and check under which serial port the board is visible.

Serial ports have the following naming patterns:

- Linux: starting with `/dev/tty`

- macOS: starting with `/dev/cu.`

If you are not sure how to check the serial port name, please refer to Establish Serial Connection with ESP32-S3 for full details.

Note

Keep the port name handy as it is needed in the next steps.

# Configure Your Project

Navigate to your `hello_world` directory, set ESP32-S3 as the target, and run the project configuration utility `menuconfig`.

    cd ~/esp/hello_world
    idf.py set-target esp32s3
    idf.py menuconfig

After opening a new project, you should first set the target with `idf.py set-target esp32s3`. Note that existing builds and configurations in the project, if any, are cleared and initialized in this process. The target may be saved in the environment variable to skip this step at all. See Select the Target Chip: set-target for additional information.

If the previous steps have been done correctly, the following menu appears:

Project configuration - Home window

You are using this menu to set up project specific variables, e.g., Wi-Fi network name and password, the processor speed, etc. Setting up the project with menuconfig may be skipped for "hello_world", since this example runs with default configuration.

Note

The colors of the menu could be different in your terminal. You can change the appearance with the option `--style`. Please run `idf.py menuconfig --help` for further information.

If you are using one of the supported development boards, you can speed up your development by using Board Support Package. See Additional Tips for more information.
